Jason needs to save at least $200 by the end of the summer. He already has $40, and he has 8 weeks to save. Which inequality can he use to decide how much he needs to save each week?
Step-by-step explanation:
y=mx+b
200 = 8x + 40
Rearrange,
x = 160/8 = 20
He would need to save $20 a week
200= 20 × 8 + 40
Answer:
8x + 40 ≥ 200At least $20 each weekStep-by-step explanation:
Target amount = at least $200Jason already has = $40Time = 8 weeksSaved amount each week = xRequired inequality:
8x + 40 ≥ 2008x ≥ 160x ≥ 160/8x ≥ $20Plot the points (-6,8) and (0,8) on the coordinate plane below.
What is the distance between these two points?
units
The points (-6,8) and (0,8) are coordinate points, and the distance between the points (-6,8) and (0,8) is 6 units
The distance between the two pointsThe points are given as:
A = (-6,8)
B = (0,8)
The distance between the points is calculated using:
[tex]d= \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]
So, we have:
[tex]d= \sqrt{(-6 - 0)^2 + (8 -8)^2}[/tex]
Evaluate
d = 6
Hence, the distance between the points (-6,8) and (0,8) is 6 units

Wyatt is going to a carnival that has games and rides. Each game costs $1.25 and each ride costs $2.75. Wyatt spent $20.25 altogether at the carnival and the number of rides he went on is twice the number of games he played. Determine the number of games Wyatt played and the number of rides Wyatt went on.
Answer:
Wyatt played 3 games and went on 6 Rides
Step-by-step explanation:
Let games be represented as x
Let ride be represented as y
Each game cost $1.25
Each ride cost $2.75
Total money spent by Wyatt= $20.25
x1.25 + y2.75 = 20.25 ..... Equation 1
the number of rides he went on is twice the number of games he played
Y= 2x ... Equation 2
Substituting the value of y into equation 1
x1.25 + y2.75 = 20.25
x1.25 + 2(x)2.75 = 20.25
x1.25 + x5.5 = 20.25
x6.75= 20.25
x= 20.25/6.75
X= 3
Y= 2x
Y= 2(3)
Y= 6
Wyatt played 3 games and went on 6 Rides

Step-by-step explanation:
Answer:
10.5
Step-by-step explanation:
your equation: DT = DH + HT
HT = 2DH
so now your equation is DT = DH + 2DH
plug in your values: 3.5 + 2(3.5)
you get DH = 10.5
Prove that quadrilateral Q(1, 2), U(2, 5), A(5, 7) and D(4, 4) is a parallelogram by using slopes.
Slope of QU =
Slope of AD =
Slope of UA =
Slope of QD =
Which sides are parallel (give the letters) A) sides QU and AD B) sides QU and UA C) sides UA and QD D) sides AD and QD
Answer:
[tex]m = 3[/tex] ---- Slopes of QU and AD
[tex]m =\frac{2}{3}[/tex] ---- Slopes of UA and QD
Sides QU and AD have the same slope
Sides UA and QD have the same slope
Step-by-step explanation:
Given
[tex]Q = (1, 2)[/tex]
[tex]U = (2, 5)[/tex]
[tex]A = (5, 7)[/tex]
[tex]D = (4, 4)[/tex]
Solving (a): Slope of QU
[tex]Q = (x_1,y_1)= (1, 2)[/tex]
[tex]U = (x_2,y_2)= (2, 5)[/tex]
Slope, m is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m =\frac{5-2}{2-1}[/tex]
[tex]m =\frac{3}{1}[/tex]
[tex]m = 3[/tex]
Slope of AD
[tex]A =(x_1,y_1) = (5, 7)[/tex]
[tex]D = (x_2,y_2) = (4, 4)[/tex]
Slope, m is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m =\frac{4-7}{4-5}[/tex]
[tex]m =\frac{-3}{-1}[/tex]
[tex]m = 3[/tex]
Slope of UA
[tex]A =(x_1,y_1) = (5, 7)[/tex]
[tex]U = (x_2,y_2)= (2, 5)[/tex]
Slope, m is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m =\frac{5-7}{2-5}[/tex]
[tex]m =\frac{-2}{-3}[/tex]
[tex]m =\frac{2}{3}[/tex]
Slope of QD
[tex]Q = (x_1,y_1)= (1, 2)[/tex]
[tex]D = (x_2,y_2) = (4, 4)[/tex]
Slope, m is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m =\frac{4-2}{4-1}[/tex]
[tex]m =\frac{2}{3}[/tex]
Solving (b): Parallel Sides
Two sides are said to be parallel if they have the same slope.
The slope were calculated in (a) above and from there, we have the following observations
1. QU and AD have the same slope of 3
2. UA and QD have the same slope of 2/3
airplane a traveled 1273 miles in four hours.For airplane b y=621 x/2 represents rate of speed over the same four hours wichair plane traveled at a faster rate and by what factor?round to the nearest hundredth
Answer: Airplane A by a scale factor of 1.02
Step-by-step explanation:
Airplane A: 1273/4=318.25
Airplane B: Rate is the slope of equation, 621/2=310.5
So,
318.25/310.5=1.0249
Airplane 'a' is faster than airplane 'b' by a factor of 1.03 times.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An airplane 'a' traveled 1273 miles in four hours.
∴ The airplane 'a' traveled (1273/4) = 318.25 miles per hour.
For airplane b y = (621x)/2 + 0b represents the rate of speed over the same four hours
∴ The rate of change per hour for airplane 'b' is (621/2) = 310.5 miles.
So, airplane 'b' is faster than airplane 'a' by a factor of (318/25/310.5) = 1.0257 = 1.03 times.

The amount a hardware store pays for buying nylon rope is represented by the equation y = 0.08x, where 'y' is the price it pays for 'x' feet of rope. The amount the hardware store charges for selling the rope is represented by the graph. Part A What does the slope of the graph show about the hardware store's selling price for the rope?
Answer:
0.025 $/in.
The store bought 300 ft of rope.
1 ft = 12 in.
300 ft * 12 in./ft = 3600 in.
The store bought 3600 inches of rope.
The store sells 40 inches of rope for $1.60. We can find the selling unit price of rope in dollars per inch.
($1.60)/(40 in.) = $0.04/in.
The store sells the rope at a price of $0.04 per inch.
The store sold all the rope at $0.04/in.
3600 in. * $0.04/in. = $144
The store sold all the rope for $144.
The profit was $54 for selling ll the rope.
$144 - $54 = $90
The bought the rope for $90.
The cost is dollars per inch is
($90)/(3600 in.) = 0.025 $/in.
Step-by-step explanation:
The slope tells for every one-foot increase in the amount of rope sold, the hardware store increases the selling price by $0.08.
The slope of the graph represents the rate of change between the hardware store's selling price (y-axis) and the quantity of nylon rope sold (x-axis).
In this case, the slope is given as 0.08.
Interpreting the slope:
A slope of 0.08 means that for each additional foot of nylon rope the hardware store sells (x increases by 1), the selling price (y) increases by $0.08.
This indicates a linear relationship between the quantity of rope sold and the selling price.
In other words, for every one-foot increase in the amount of rope sold, the hardware store increases the selling price by $0.08.
